What is Proxy Server?

A proxy server is a specific type of application server that routes HTTP requests to content servers that perform the work. Proxy servers can be classified according to the role that it plays in a system. This specific proxy server is classified as a reverse proxy server because the main function is to act as the first point of contact, not including the firewall, for client requests into enterprise server.

Overview of the proxy server
   

Fore browser Proxy setup instructions:

You are Configure step by step :

  • Mozilla Firefox: Tools > Options > Advanced > Settings > Manual proxy configuration.
  • Google Chrome: Options > Under the hood > Network > Change proxy settings > LAN settings > Use a proxy server > Advanced > HTTP.
  • Internet Explorer: Tools > Internet options > Connections > LAN settings > Use a proxy server > Advanced > HTTP.
  • Opera: Tools > Preferences > Advanced > Network.

Anonymity levels

  • Level 1: No anonymity; remote host knows your IP and knows you are using proxy.
  • Level 4: Low anonymity; remote host does not know your IP, but it knows you are using proxy.
  • Level 8: Medium anonymity; remote host knows you are using proxy, and thinks it knows your IP, but this is not yours (this is usually a multihomed proxy which shows its inbound interface as REMOTE_ADDR for a target host).
  • Level 16: High anonymity; remote host does not know your IP and has no direct proof of proxy usage (proxy-connection family header strings). If such hosts do not send additional header strings it may be considered as high-anonymous. If a high-anonymous proxy supports keep-alive you can consider it to be extremely-anonymous. However, such a host is highly possible to be a honey-pot.

Planet Lab / CoDeeN

PlanetLab proxy servers marked with a icon are from the Planetlab CoDeeN (CDN) Project, a network of educational Internet nodes at Princeton University. These proxies may force a captcha and allocate you a different IP address as advertised.

Security notes

Our proxy list database consists of third-party 'open proxies'; proxy servers set up for public use. We have absolutely NO control over any of these proxy servers and can not vouch for security, therefore USE OUR DATABASE AT YOUR OWN RISK. For a guaranteed secured encrypted connection, private servers in our control, reliable fast speeds and multiple servers world-wide we recommend you use our VPN service.

Other system in Internet Explorer 6.0 v Browser :

  1. On the Tools menu in Internet Explorer, click Internet Options, click the Connections tab, and then click LAN Settings.
  2. Under Proxy server, click to select the Use a proxy server for your LAN check box.
  3. In the Address box, type the IP address of the proxy server.
  4. In the Port box, type the port number that is used by the proxy server for client connections (by default, 8080).
  5. You can click to select the Bypass proxy server for local addresses check box if you do not want the proxy server computer to be used when you connect to a computer on the local network (this may speed up performance).
  6. Click OK to close the LAN Settings dialog box.
  7. Click OK again to close the Internet Options dialog box.

Browser Internet Explorer 5v

  1. Click Start, point to Settings, click Control Panel, and then double-click Internet.
  2. Click the Connections tab, click LAN Settings, and then click to select the Use Proxy Server check box.
  3. In the Address box, type the appropriate proxy server information, and use the following format:
    http://<address>
  4. Click Advanced, and then type the appropriate proxy settings in the Servers area. Use the following syntax for the proxy settings:
    http://<address>:<port>
    where <address> is the Web address of the proxy server, and <port> is the port number that is assigned to the proxy server. For example, if the proxy server's address is "proxy.example.microsoft.com" and the port number is 80, the setting in the Proxy Server box should appear like this:
    http://proxy.example.microsoft.com:80
    Important: If you use a backslash (\) instead of a slash (/) in the proxy server's address, the settings disappear from the Proxy Server box and Internet Explorer does not find the proxy server.

    If you are using the Internet Protocol (IP) address of your proxy server, make sure not to type leading zeros. For example, use 130.25.0.1 instead of 130.025.000.001.

    If you do not know the Web address or port number of the proxy server, contact your network administrator. Also, if there are any Web servers on the local network for which you want to bypass the proxy, type the appropriate host names in the Don't Use Proxy For These Addresses box. For example, if you do not want to use the proxy server to obtain access to the "example.com" Web server on your LAN, type example.com in the Don't Use Proxy For These Addresses box.

Internet Explorer 4.0, 4.01 for Windows 95 and Windows NT

  1. Click Start, point to Settings, click Control Panel, and then double-click Internet.
  2. Click the Connection tab, and then click to select the Access the Internet using a proxy server check box.
  3. Click Advanced, and then type the appropriate proxy settings in the Servers area. Use the following syntax for the proxy settings
    http://<address>:<port>
    where <address> is the Web address of the proxy server, and <port> is the port number that is assigned to the proxy server. For example, if the proxy server's address is "proxy.example.microsoft.com" and the port number is 80, the setting in the Proxy Server box should look like this:
    http://proxy.example.microsoft.com:80
    Important: If you use a backslash (\) instead of a slash (/) in the proxy server's address, the settings disappear from the Proxy Server box and Internet Explorer does not find the proxy server.

    If you are using the Internet Protocol (IP) address of your proxy server, make sure that you do not type leading zeros. For example, use 130.25.0.1 instead of 130.025.000.001.

    If you do not know the Web address or port number of the proxy server, contact your network administrator. Also, if there are any Web servers on the local network for which you want to bypass the proxy, type the appropriate host names in the Don't Use Proxy For These Addresses box. For example, if you do not want to use the proxy server to access the "example.com" Web server on your LAN, type example.com in the Don't Use Proxy For These Addresses box.
